Small leaks easier to find, because to create a vapor-like smoke the machine heats the mineral oil, it may contain dye of UV leak detection. Cycle the purge solenoid and other EVAP self-test can be run using a professional level scan tool which have a bidirectional communication ability. 1. Low Fuel Pressure
How do you pass the OBD-2 emissions test?
To pass an OBD-II emissions test, a vehicle must: If you clear the ‘Check Engine’ light, or reset the OBD-II monitors right before your emissions test, your vehicle typically will not pass because the catalyst and EVAP monitors need time to run.

The monitors are reset whenever the battery is disconnected. Clearing diagnostic trouble codes (DTCs) from the computer’s memory also resets the monitors.
